/* After emitting to a sequence, restore previous saved state.

   To get the contents of the sequence just made, you must call
   `get_insns' *before* calling here.

   If the compiler might have deferred popping arguments while
   generating this sequence, and this sequence will not be immediately
   inserted into the instruction stream, use do_pending_stack_adjust
   before calling get_insns.  That will ensure that the deferred
   pops are inserted into this sequence, and not into some random
   location in the instruction stream.  See INHIBIT_DEFER_POP for more
   information about deferred popping of arguments.  */
